La 1-x Sr x NiO 3 (x= 0.0, 0.3 or 0.7) perovskite-type oxides were synthesized using the modified proteic gel method and using collagen as an organic precursor. Catalysts of La 1-x Sr x NiO 3 /Al 2 O 3 were obtained using the wet impregnation method. The synthesized catalysts were characterized by X-ray diffraction, surface area and temperature-programmed reduction. The catalysts were evaluated in the partial oxidation reaction of methane, and the levels of selectivity to CO, CO 2 , H 2 and H 2 O were determined. Among the catalysts studied, the catalyst LaNiO 3 /Al 2 O 3 had the highest methane conversion level (78%) and higher H 2 selectivity (55%). Keywords: La 1-x Sr x NiO 3 , perovskite-type oxides, modified proteic gel method, partial oxidation of methane. Resumo Perovskitas do tipo
